Is this Yunnan's most beautiful valley? High up from the steamy lowlands of Dehong, nestled between two mountain ranges lies Husa Valley, home of the Achang. The Achang, one of Yunnan's smallest ethnic groups, are believers in Buddhism as the many temples dotted around the valley testify. Exploring the villages you are bound to be invited into their home, for the Achang are proud to show off their customs and must rank as some of the most hospitable people around.
